It wouldn't work - client would debug unless you edit Tibia.spr (and possibly Tibia.dat) and add a new shootType.well, the spirte is already created, i would use the arrow going up-right for all directions but in the source, there's something like SHOOT_EFFECT_CAKE = 0x29
this 0x29 defines what sprite will be used, how can i know wich is crystal arrow
